In addition to the energy density, the low cost of zinc-based flow batteries and electrolyte cost in particular provides them a very competitive capital cost. Taking the zinc-iron flow battery as an example, a capital cost of $95 per kWh can be achieved based on a 0.1 MW/0.8 MWh system that works at the current density of 100 mA cm-2 .
The history of zinc-based flow batteries is longer than that of the vanadium flow battery but has only a handful of demonstration systems. The currently available demo and application for zinc-based flow batteries are zinc-bromine flow batteries, alkaline zinc-iron flow batteries, and alkaline zinc-nickel flow batteries.
A novel zinc-air flow battery is first designed for long-duration energy storage. A max power density of 178 mW cm −2 is achieved by decoupling the electrolyte. Fast charging is realized by introducing KI in the electrolyte as a reaction modifier. Zinc dendrite and cathode degradation can be alleviated at lower charging voltage.
Indeed, not all zinc-based flow batteries have high energy density because of the limited solubility of redox couples in catholyte. In addition to the energy density, the low cost of zinc-based flow batteries and electrolyte cost in particular provides them a very competitive capital cost.
